Abstract (en)
[origin: WO2023274963A1] A calibration standard (70) for measuring the angle between an optical axis (34) of an autocollimator (22) and a mechanical linear axis (46), along which an object (45; 92) is linearly movably arranged, includes an at least partly reflective planar surface (73) and a refractive surface (S) which is at least substantially spherically curved and reflects off the planar surface (73).
